This is my first attempt at building openHAB (openhab-webui only). I am not sure yet of what I’m actually doing 
and might be missing prerequisites that are obvious to devs such as env variables I might need to set. So bare with me. Consider my build system to be ‘virgin’.
I followed Developer Guide | openHAB and openhab-webui/CONTRIBUTING.md at main · openhab/openhab-webui · GitHub
My builds using variants of mvn clean install -o -e -X -DskipChecks now fail because the build run tries to install some version of nodejs it cannot find for download.
I don’t understand why it tries to at all, though. As seen below nodejs and npm are there.
I also manually updated them. I tried on debian x86 and Raspi OS, same error.
How do I tell the build process to use the installed nodejs/npm ?
markus@emspc:/volatile/work/openhab-webui $ nodejs --version
v16.15.1
markus@emspc:/volatile/work/openhab-webui $ npm --version
8.11.0
